Zeek then want to ride his bike to the old spaghetti factory. He wondering if he should bike 1 mile north, then 0.5 miles direct
frosja888 [35]

Answer:

He should travel directly

Step-by-step explanation:

Given

x = 0.5 --- East

y =1 --- North

If he goes through east north direction, the distance (d) traveled is:

d = x + y

d = 0.5 + 1

d = 1.5 mile

If he travels directly, the distance (d) is:

d = \sqrt{x^2 + y^2} ---- Pythagoras theorem

d = \sqrt{0.5^2 + 1^2}

d = \sqrt{0.25 + 1}

d = \sqrt{1.25}

d = 1.12mile

By comparison, he will travel the shortest distance if he travels directly because 1.12 < 1.5

<em>Hence, he should travel directly</em>
